Добрый день,
На сервере отключен IPv6. На nginx настроено проксирование на upstream c
поддержкой IPv4 и IPv6.
Nginx периодически (раз в 5 секунд) пытается отправлять запросы на IPv6 и
соответственно обламывается с ошибками:
2013/07/30 00:25:06 [error] 1930#0: *1482670 connect() to
[AAAA:BBBB:C:DDD:E:F:GGG:HHH]:443 failed (101: Network is unreachable) while
connecting to upstream, client: AA.BB.CC.DD, server: example.com, request:
"GET /download/file HTTP/1.0", upstream:
"https://[AAAA:BBBB:C:DDD:E:F:GGG:HHH]:443/download/file";, host:
"example.com"
Как можно отключить IPv6 для proxy_pass?
# nginx.conf:
upstream download {
server download.example.com:443;
keepalive 8;
}
location /download {
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Connection "";
proxy_ignore_headers X-Accel-Redirect;
proxy_http_version 1.1;
resolver 8.8.8.8;
resolver_timeout 5s;
proxy_pass https://download;
}
